Break-in oils
The final step in building an engine is starting it for the first time.

Driven break-in engine oils are specially formulated for break-in and provide the best foundation for high power, cooler running and longest life for your new, reconditioned or rebuilt engine. Also use for new camshaft installations/replacements.

Our break-in oils are designed to ensure optimum performance during the critical initial stages of engine operation. With advanced formulations, these oils provide superior lubrication and controlled wear, making them the perfect choice for new builds or rebuilds.

Designed to seal rings quickly and protect components, our engine break-in oil provides unmatched reliability. Driven Racing Oil’s break-in oils provide the foundation for long-lasting engine performance and durability.

High ZDDP levels and ultra-low detergent levels optimized for running in both flat tappets and roller camshafts.

Formulated to provide “controlled wear” between the cylinder wall/ring interface while maintaining wear protection and faster ring sealing.

We recommend that you drive our break-in products for the first 30 minutes, then drain the oil and replace it with new break-in oil and change the filter. Drive for a maximum of 480 km.

BR30 SAE 5W-30 Break-in oil

Same high zinc and phosphorus formula as our original break-in oil, now in a 5W-30 viscosity for modern rebuilt and hydraulic lift engines. Provides excellent ring sealing. Does not require additional ZDDP additives. Great for full power on the dyno, a night of racing or up to 400 miles on the street.

Driven Racing Oils are formulated for classic and racing applications only. This engine oil does NOT meet any current API or OEM engine oil specifications. These oils are not intended for vehicles equipped with catalytic converters.

BR50 SAE 15W-50 Break-in oil

This unique petroleum oil, recommended by several camshaft manufacturers, provides optimal levels of zinc and phosphorus for flat tappets and aggressive roller valves, and the additive package promotes ring sealing. Provides maximum protection for cams and tappets during initial break-in. Requires no additional ZDDP additives. Good for full power on the dyno, a night of racing, or up to 400 miles on the street. Viscosity typical of 15W-50.
